SPECIFICATION forming part of Letters Patent No. 644,246, dated February27, 1900. Application filed November l5, 1899. Serial No. 737,069. (Nomodel.)

To all whom, t 'may concern:

Be it known that I, GEORGE W. GLAZIER, a citizen of the United States,residing at 389 Lafayette street, Salem, in the county of Essex andState of Massachusetts, have invented new and useful Improvements inPaper-Box- Covering Machines, of which the following is a specification.

This invention relates to improvements in paper-box-covering machinesfor the purpose of covering theI tops of paper boxes with a pasted stripof paper and cutting off the same to the desired length required forcovering the top of the cover portion of the box, as will hereinafter bemore fully shown and described, reference beingl had to the accompanyingdrawings, wherein- Figure 1 represents a longitudinal sect-ion of theimproved machine, parts being shown in elevation. Fig. 2 represents adetail side elevation of the head of the machine, showing theconstruction and arrangement of the paper-strip-cutting-off device. Fig.3 represents a top plan view of Fig. 2. Fig. 4 represents across-section of Fig. 3, showing the oscillating knife in position forcutting off the pasted paper strip and showing the boxsupporting blockswung to its rear position. Fig. 5 represents an end elevation of Fig.2; and Fig. 6 represents a cross-section on the line 6 6, shown in Fig.3.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In Fig. l, A represents the paste-containing receptacle, and Brepresents the pastingroller loosely journaled in bearings on saidreceptacle, as usual.

C represents the paper-reel, arranged on a spindle loosely journaled inbrackets attached to the frame of the machine, as is coinmon in devicesof this kind.

C is the paper strip, which is carried from the reel C in contact withthe tension-bar D, and from there it is brought in contact with theupper portion of the rotary pasting-roller B, Where said strip is pastedon its under side and conducted partially around the roller E I wish tostate that I do not claim the mechanism as above described, as such iswell known in box-pasting machines and is only referred to for thepurpose of properly describing the general operation of machines of thiskind.

To the front of the paste-receptacle A is secured in a suitable mannerthe head I, the upper sides of which are inclined toward the front endof the machine, as shown in the drawings. To the said upper-inclinedsides of the head I are adj ustably secured bearings K K, in which arejournaled the end trunnions Z Z of the inclined or spiral frame L, towhich the spiral or inclined movable cutter L is secured, as shown.

To the trunnion Z is secured a lever M, to which is connected the upperend of a spring N, the lower end of which is attached to the head I forthe purpose of automatically holding the knife L and its frame in theraised position shown in Figs. l, 2, and 5. To the opposite trunnion Zis secured a lever O, to which is pivotally connected a link O', whichmay be depressed by means of a treadle-lever connected to it for thepurpose of swinging the movable knife L against the stationary knife Pduring the operation of cutting off the paper strip C, as is common indevices of this kind. The said treadle mechanism is not representedinthe drawings, as itis awellknown feature in machines of this kind anddoes not form subject-matter of my present invention.

P is the stationary knife, which is secured in a suitable manner to across-bar P', the ends of which are pivotally connected to the sides ofthe head I, as shown at p in Figs. 2, 4, 5, and 6, so as to permit thecutting edge of said stationary knife to be adj usted relative to thecutting edge of the movable knife L', so as to compensate for any wearthat may occur from time to time on said knives.

Integral with each end of the cross-bar P is made a lever or projectionP", and in connection therewith I make use of an adjusting deviceconstructed as follows: Through the upper portion of the head I isinserted a screwbolt Q, passing loosely through a perforation in thelever or projection P and provided at its lowerend with a nut q, asshown in Fig. 6.

R is a set-screw screwed through the upper portion of the end of thehead I and having its lower end pressing against the upper portion ofthe lever P", as shown in said Fig. 6.

To adjust Ithe position of the stationary knife P relative to themovable knife L, it is only necessary to adj ust the positions of thescrew-bolts Q and R by loosening the one and tightening the other, orvice versa, as circumstances may require.

To one side of the head I is secured in an adjustable manner a bracketS, to which is longitudinally adjustably secured a spindle S', on whichis pivotally arranged an arm or bracket S, located between a collar S3and lever S", secured to the spindle S, as shown in Figs. l, 2, 3, and5. In the bracket S is longitudinally adjustable a spindle T, which maybe secured in its adjusted position by means of a set-screw t, as shown.To the upper end of said spindle T is secured the box former or block U,adapted to receive the box V the top of which is to be covered, asshown. The bracket S" is provided with a stationary stop S5 and anadjustable set-screw stop S6 for the purpose of limiting the oscillatingadjustment of said bracket and box-former attached to it during theoperation of covering the top of the box V held on the box-former Uduring the covering operation.

In practice I make on-the front portion of the stationary knife-holdin gbar P a cut-away portion 19 to enable the box-former U and the box heldthereon to be swung backward relative to the stationary knife P, inclose proximity to the latter, so as to enable the pasted paper strip tobe cut off the proper length required for the covering of the top of thebox V.

Back of the stationary knife P is arranged a yielding metal bar W,connected by springs w w to the rear of the head I, and said yieldingmetal bar WV serves for the purpose of holding the pasted strip C raisedabove the stationary knife P at all times except at the moment ofsevering the same, thus preventing the pasted under side of said stripfrom being dragged over the upper edge of the said stationary knife, andthereby preventing' the latter from being fouled by the paste, as wellas preventing the paste on the under side of the paper strip from beingscraped off by contact with said knife.

It will be noticed that in this my improved box-coveringv machine themovable knife L is pivotally arranged above the stationary knife P andpivoted behind the latter in such a manner as to enable the operator toreadily take hold of the end of the pasted strip while the movable knifeis held raised after a desired length of strip has been cut off. It willalso be noticed that the stationary knife P is arranged in an inclinedposition, by which arrangement the box-former U can be tipped backwardin such a position during the cutting off of the pasted strip as tocause the latter to be cut olf to the proper length for covering the topof the box.

By having a cut-away portion on the stationary knife-holdin g bar P' therear edge of the said box-former can be swung directly below the cuttingedge of the stationary knife, thus facilitating the placing of thesevered strip properly onto the box to be covered.

The operation of the machine is as follows: Normally the movable knife Lis held by the iniiuence of the spring N in the raised position shown inFigs. l, 2, and 5 and the boxform er U is held in the outward positionshown in Figs. 2 and 3. The operator then places the box V upon thebox-former U and swings it to the position shown in Figs. l and 4 andtakes hold of the end of the pasted strip C resting on the yieldingsupport W and pulls it forward and places it onto the top of the box V,after which the link O is depressed, causing the movable knife L' to beswung forward in the direction of the arrow shown in Fig. 1 to theposition shown in Fig. 4, causing the strip C to be severed, after whichthe operator releases his hold on the link O', causing the spring N toreturn the movable knife L to its normal position. (Shown in Figs. l,2,and 5.) The operator then swings the box-former to the position shownin Fig. 2, smooths down the strip upon the top of the box, and removesthe latter preparatory to the placing of another box onto said boxformerto be covered, and so on during the operation of the machine. By havingthe movable knife L pivoted back of the stationary knife P and above thelatter the operator is enabled readily to take hold of the end of thepasted strip C' and to draw it forward, so as to place it in positiononto the box previous to cutting off said strip the desired lengthaccording to the size of the box that is to be covered. By having thestationary knife P secured at an angle to the vertical and inclinedtoward the front of the machine the box-former may be swung backward, sothat its rear end will come directly below the cutting edge of thestationary knife, thus enabling the strip to be cut off the properlength for covering the top of the box.

Vhat I wish to secure by Letters Patent and claim isl. In an organizedpaper-box-covering machine, in combination, an oscillating knife L,pivotally arranged above and in rear of a stationary inclined knife Psecured to a pivotally-adjustable bar P', having a front cutaway portionp adapted to receive the rear portion of the box-former and box heldtheregn, substantially as and for the purpose set ort 1.
